Therefore, GCD of numbers 336, 555, 21, 568 is 1

Given Input Data is 336, 555, 21, 568

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 336 is 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 21 is 3 x 7

Prime Factorization of 568 is 2 x 2 x 2 x 71

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(336, 555) = 62160

GCD(336, 555) = ( 336 x 555 ) / 62160

GCD(336, 555) = 186480 / 62160

GCD(336, 555) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 21

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(3, 21) = 21

GCD(3, 21) = ( 3 x 21 ) / 21

GCD(3, 21) = 63 / 21

GCD(3, 21) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 568

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(3, 568) = 1704

GCD(3, 568) = ( 3 x 568 ) / 1704

GCD(3, 568) = 1704 / 1704

GCD(3, 568) = 1

GCD of 336, 555, 21, 568 is 1
